Show that Black-Scholes call option hedge ratios also increase as the stock price increases. Consider a 1-year option with exercise price $50, on a stock with annual standard deviation 20%. The T-bill rate is 3% per year. Find N(d1) for stock prices (a) $45, (b) $50, and (c) $55.
3) Suppose that the price of a non-dividend-paying stock is $27, its vo itility is 20%, and the risk-
free rate for all maturities is 6% per annum. Provide a table showing the relationship between profit
and final stock price for a butterfly spread using European put option with strike prices of $20,
$25, and $30 and a maturity of one year. Ignore the impact of time a e of money.
The price of a share follows the geometric Brownian motion with parameters µ = 0.2 and σ = 0.18. Presently, the share’s price is £38. Consider a call option having one year until its expiration time and having a strike price of £40. The continuously compounded interest rate is 5%.
(a) What is the risk-neutral price C of this call option?

- Consider a stock with a current price of P = $27.Suppose that over the next 6 months the stockprice will either go up by a factor of 1.41 or downby a factor of 0.71.

Assume that the risk-free rate is 3% per year. Also assume the stock does not pay a dividend. Pick the closest number.arrow_forwardA power option pays off [max(S₁ - X),01² at time T where ST is the stock price at time T and X is the strike price. Consider the situation where X = 26 and T is one year. The stock price is currently $24 and at the end of one year it will either $30 or $18.

- Give typing answer with explanation and conclusion A call option has a strike price of $11, and a time to expiration of 0.8 in years. If the stock is trading for $20, N(d1) = 0.5, N(d2) = 0.12, and the risk free rate is 5.40%, what is the value of the call option?arrow_forwardConsider a stock with a current price of $15 that will be worth either $10 or $25 1 year from now. Assume rf = 0% (annual compounding). You have invented a new derivative security called an "inverse", whose payoff in 1 year is 100 divided by the stock price, i.e., payoff =100/S1 . If the beta of the stock is 1.2, what is the beta of this new derivative?arrow_forwardA call option has X=$52 and expire in 360 days (suppose we have 360 days in one year). The risk-free rate is 4%. The call is priced at $11. A put option has X-$52 and is priced at $1. The underlying asset is priced at S0=$43.
